To all wlwmz'tmay concern:

Be it known that I, GEORGE PoLLooK, a citizen ofthe United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Methods of Making Shoes, of whichthe followingis a specification. v The object ofmy invention is to provide a method of making shoes which will be less expensive than those heretofore used in the amount of capital required for the manufacture, in the cost of labor employed, and in the amount of material consumed, and which will. result in the formation of a more comfortable shoe than those made by previous methods.

In the accompanying drawing, Figure 1 is a plan view of a shoe made according to my improved method; Fig. 2 is an enlarged cross sectional View on the line 2-2 of Fig. 1.; Fig. 3 is a similar view illustrating the first stage in the manufacture of the shoe; Fig. 4 is a similar view illustrating the second stage thereof.

yimprovement, refers only to themak ing of the front portion of the shoe, the rear portion being made according to methods now in use. i

I first cutout the sole land I also form an upper without molding,lasting, or stretching the leather of the upper in any manner whatever. The first operationin so forming the upper is to cut inner and outer upper sections 3*, 3" of flat pieces of leather and of proper shape in that the inner longitudinal edges of these sections are curved convexly to each other at their extreme front portions, so that, when said inner edges are stitched together, thereby forming a hollow body having a longitudinal seam 5, while the rear portion of said seam slopes gently downward toward the toe portion of the.

upper, the downward inclination of said seam increases more and more as it extends forwardly, until at an extreme front portion it becomes approximately vertical.

The sections 3*, 3 are unequal in width, the

inner section 3 being the narrower,,so that said seam extends in a direct line between the toe and the heel. They are carefully cut of such form and size that, when they are'so stitched together, the free marginal portion of the upper so formed can be laid down with the under side downward, so that its edge, laid flat on the sole, and without being turnedinward as in lasting an upper to a sole, exactly registers with the edge of the sole, and that the volume then inelosed by theupper and sole is substantially that of the foot to be fitted.

Havingv prepared inner and outer sections 3*, 3", of the propersize and shape as above explained, they are stitched together along their inner longitudinal edges to form the and the marginal portion of the sole 1 thus cemented together. The formation of the front portion of the shoe is then completed. They-heel portion of the shoe is made by turning. in or under upon the heel the leather forming the upper part of the shoe and securing thereto a counter in the usual manner.

A last is inserted in the shoe to raise the front portion of the upper to the proper shape. I r

It will therefore be seen that by my improved process I effect saving in material used for making the upper, since the said material is not so wide as before, the use of an insole andv six machines, namely, (1)

the grooving'machine. which cuts the groove in the insole, (2) the lasting machine, which is used for stretching the upper over the last, (3) the welting machine, which is used to secure together the welt, upper and insole, (4) the welt beating machine, (5) the welt trimming machine, (6) I the rough rounding machine. I use a stitching mastallation of machinery, less labor, because 1 chine for stitching the welt, upper and sole e there are fewer machines tooperate, and less material, since the blanks from which the upper is formed are cut the exact size-f required, and there is no loss in trimming OK the edge of the upper.

It is obvious that an inferior form of-my' improved method would be to cut the upper of such formthat-itwould extend slightl within the edge of the sole, but not toomuc so as tdprevent the'succeeding stepsof the process being carried out according to my invention; or apart from that it would eXf tend a certain definite distance, say, a quarter of an inch, beyond the edgeof thesole' when placed thereon and then proceeding according to my'method, and trimming all the portion of the upper projecting beyond the so1e.- I do not eonsiderlthesel methods as departures from myinvention. VAs to the last named I do notconsider such project ing portionto constitute any part of the upslon thereof.

I claiin: v The method of forming a shoe which conper, proper, but a mere superfiuous extensistsof forming a sole and'upper sections. having the extreme front portions of their toward each inner edges curved convexl other, said-sections being 0 such s'izeand form thattheir outer'edges can exactly reg} "i'ster with the edge of the sole, and that,
